Refrigerant - Mercedes-Benz CLA Operator's Manual

The antifreeze concentrate/corrosion inhibitor
concentration in the engine cooling system
should:
be at least 50%. This will protect the engine
R
cooling system against freezing down to
approximately -35 ‡ (-37 †)
not exceed 55% (antifreeze protection down
R
to -49 ‡ [-45 †]). Otherwise, heat will not be
dissipated as effectively
Mercedes-Benz recommends a coolant or cor-
rosion inhibitor/antifreeze concentrate in
accordance with
MB Specifications for Service Products 310.1.
i
When the vehicle is first delivered, it is filled
with a coolant mixture that ensures adequate
antifreeze and anti-corrosion protection.
i
The coolant is checked with every mainte-
nance interval at a qualified specialist work-
shop.

Climate control system refrigerant
Important safety notes
The climate control system of your vehicle is fil-
led with refrigerant R‑134a.
The instruction label regarding the refrigerant
type used can be found on the left, on the under-
side of the hood.
!
Only the refrigerant R‑134a and the PAG oil
approved by Mercedes-Benz may be used.
The approved PAG oil may not be mixed with
any other PAG oil that is not approved for
R-134a refrigerant. Otherwise, the climate
control system may be damaged.
Service work, such as refilling with refrigerant or
replacing component parts, may only be carried
out by a qualified specialist workshop. All appli-
cable regulations, as well as SAE standard J639,
must be adhered to.
Always have work on the climate control system
carried out at a qualified specialist workshop.
